CROSS-HEAD FEED FOR SHAPING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 71 dated December 1902-Applicatitn filed August 12, 1901. Serial No. 71,739.

To aZZ whom it may concern.-

Be it known that I, GEORGE J. ll/IEYER, a citizen of the United States,residing at 407 Florida street, Milwaukee, county of Milwau- 5 kee, andState of Wisconsin, have invented certain new and useful Improvements inCross-Head Feeds for Shaping-Machines having Vertical Tool-Slides, fullydescribed and represented in the following specification and to theaccompanying drawings, forming a part of the same.

The present improvements relate to that class of shaping-machines inwhich the frame is provided upon the top with a reciprocating i 5 ramand upon the front with a horizontal crosshead having means'foradjusting it vertically beneath the ram, which carries atool-slide tomove the tool at right angles to the cross-head. Such cross-head isprovided with a carriage 2b to support the Work-piece beneath the tool,and a bracket-table is commonly attached to such carriage and used withor without a vise to support certain kinds of work-pieces; but suchtable is usually made detachable from 2 5 the carriage, so as to permitthe fastening of other kinds of work-pieces directly to the face of thecarriage. Heretofore the feed for the table has been furnished by ascrew extended lengthwise of the cross-head, and in such class ofshaping-machines when it is necessary to feed the table along by hand ithas commonly been effected by a handle fitted to the screw at theextreme end of the cross-head.

This invention provides a convenient means 3 for the operator to actuatethe horizontal or table feed, while at the same time operating thevertical feed of the tool-slide.

In shaping-machines it is frequently necessary for the operator to feedthe tool ver- 40 tically and at the same time feed the carriage andwork-piece horizontally to form oblique and curved surfaces upon thework-piece, and great difficulty is found in reaching with one hand tothe end of the cross-head in such shaping-machines to operate thehorizontal feed, while at the same time reaching with the other hand tothe vertical feed-screw upon the ram, which is in constant motion whileoperating the tool. Such use of two hands often places the body of theoperator in a position (No model.)

very inconvenient to watch the work-piece where the tool is operating todiscover and regulate the feed in the required manner. This difficultyin the operating of shapingrnachines is greatly increased Where theoperator is seated, so as to watch the work readily, as he cannot insuch position easily reach the screw-handle at the end of the cross-headwhile operating the vertical feed-screw upon the reciprocating ram.

Shapingmachines are especially used to form intricate shapes andsurfaces by the operation of the tool, and the means heretofore providedto manipulate the cross-head feedscrew often forces the body away fromthe work-piece, so that the workman is unable to Watch the operation ofthe tool in the needful manner without making continuous and painfulefiort. To obviate this difficulty, I provide the carriage with arotatable nut fit- 7o ted to the feed-screw of the cross-head, and Ialso furnish the carriage with a feed-spindle geared to such nut andprojected through an aperture in the carriage into a convenient positionto be turned by one hand of the operator while using the other hand towork the vertical feed. .This construction brings the handles of boththe vertical feed-screw and the horizontal feed-screw sustantially inline with the tool, so that While the operator is grasping the saidhandles he can also readily inspect the operation of the tool. Theoperators body is thus brought into a natural position in relation tothe work-piece. Such a rotatable nut has been used upon the feedscrew ofa lathe or milling-machine; but the construction required in myinvention is peculiar in that the shaping-machine is provided with avertical feed-screw as Well as a horizontal feed-screw, so as to requirethe use of both 0 hands at once. The construction in the pres ent casealso differs from those referred to in sometimes requiring thedetachment of the table from the carriage, so that the means for turningthe screw in connection with the 5 table must be removable therewith.

In the annexed drawings the invention is shown applied to ashaping-machine.

Figure l is a front elevation of the machine. Fig. 2 is a horizontalsection upon a 10c larger scale of the carriage and part of thecross-head inverted, and Fig. 3 is a vertical section of the cross-headand carriage through the center of the auxiliary feed-spindle with analternative construction for the latter. Fig. 4 shows anotheralternative construction.

The shaping-machine frame a is shown supporting the cross-head b and ram0, which carries the vertical tool-slide d. This slide is fed downwardby screw e, having handlef, and carries the tool g. The carriage his fedupon the cross-head by a horizontal screw 2',

having handlej at the end and furnished also with gearing to turn itautomatically when planing flat surfaces. The gearing shown consists ofcog-wheels 7s and a pawl m, vibrated by a lever m through the agency ofa reciprocating connection 01. in a manner well known. Such gearing isfitted to the feedscrew at the end of the cross-head and necessarilycrowds the handle j still farther from the tool and from the handle ofthe vertical feed-screw e. The carriage h is shown provided with a tablep, carrying a vise q, and a die 0 is shown in the vise with curvedsurfaces, requiring the simultaneous feeding of the tool in bothdirections. The nut o" of the cross-head screw is shown fitted torevolve in a bearing 7L2 upon the carriage and connected by gears s witha spindle t, which is carried in a bearing r upon the carriage or table.When the screw i is turned by the handle j, the nut stands still and thecarriage is fed by the screw; but when the nut is turned by the spindlet the screw stands still and the carriage is fed by the nut.

The spindle i is shown detachable from the gearing of the nut s byseveral constructions, Fig. 2 showing the inner end of the spindlefitted to a socket in the hub of one of the gears and removabletherefrom, while Figs. 3 and 4 show one of the gears attached to thespindle and removable therewith. In Fig. 2 one of the gears s is shownformed upon the end of the nut r and the other gear is shown formed witha hub fitted to a bearing in the carriage h. This hub is formed with arecess or socket to which the inner end of the spindle t is fitted, anda collar 25 is shown next the end of the hub to rest upon the face ofthe carriage. A stud or key 3' upon the spindle fits a notch in theouter end of the hub, and thus drives the same when the spindle isengaged with the gear, while it permits the removal of the spindle fromthe socket in the gear at pleasure. A bolt 11. is extended through thespindle and is threaded into the gear at the bottom of the socket. Thebolt has a head at its outer end, thus serves to draw the spindle firmlyinto the socket upon the gear and clamp the two together, the spindleand its key then operating to rotate the nut when the spindle is turned.The collar 15 is clamped by the bolt upon the outer end of the hub ofthe gear and turns against the outer side of the carriage, so that thegear and collar hold the spindle from longitudi nal movement in oppositedirections. The spindle is formed with a handle w, by which the operatorturns it.

When it is required to bolt a work-piece directly upon the carriage, itis necessary to remove the table and vise, and the removal of the boltto permits the spindle t to be removed at the same time, as it detachesthe spindle from the socket in the gear 3. When the spindle is removed,the carriage is fed by turning the screw i, and the nut is then heldfrom rotation by the thumb-screw 1) or other suitable means.

Fig. 3 shows the spindlet connected permanently to the gear 3 andcarried in a tubular bearing 2?, which is bolted detachably to thecarriage. A hole h, large enough to pass the gear, is formed in thecarriage beneath the foot of the bearing 15 and the bear ing, with thegear and spindle, can thus be removed whenever necessary.

By locating the spindle for the horizontal feed beneath the tool andwork-piece the hands of the operator can be reversed and he can work thevertical feed-with his right hand and the horizontal feed with his lefthand by grasping the handle 10, and his body is thus brought close tothe tool and into a position where he can inspect the work-piece withouttwisting himself uncomfortably, as heretofore.

In Fig. 4.- the spindle t is mounted obliquely, so as to be projectedthrough a bearing 19 in one of the flanges p, which extends downward tosupport the table 19.

The foot of the table, by which it is attached to the carriage h, isalso formed with an inclined bearing p and the spindle is thus supportedat both ends. This oblique arrangement of the spindle brings it to oneside of the center of the vise q and renders it more convenient to reachin certain cases. With such oblique arrangement of the spindle it may beconnected to the nut r by spiral gears 8 as shown in Fig. 4, or by asuitable arrangement of bevel-gears, as it is immaterial to theinvention how the spindle is connected to the nut to rotate the latter.

A hole h is shown in the carriage, adjacent to the bearing 19 to passthe gear through the same, and the bearing 19 is extended into such holeto the hub of the spiral gear. A hole is necessarily formed through thefoot of the table to pass the spindle into the hole h, and with theconstruction shown in Fig. at the spindle remains in such hole when thetable is removed from the carriage; but with the construction shown inFig. 3 the spindle-bearing 25 is detachable from the carriage separatelyfrom the table. The handle to is shown detachable from the shaft 15 inFigs. 3 and 4, and the handlej upon the end of the screw 11 is alsocommonly made detachable, and, if desired, the spindle i may be formedwith a square upon the end to fit the handle 9', so that such handle maybe used to turn the screw whether applied to the spindle or directly tothe screw itself. It will be observed that the addition of the auxiliaryspindlet does not interfere in any way with the automatic operation ofthe feed by the cog-wheels 7c when desired nor with the normal use ofthe handle j upon the horizontal feed-screw, as the friction of the nut,its gears s, and the spindle t generally suffices to hold the nutstationary when the feed is effected'by turning the screw.

It will be observed in Fig. 1 that the spindle if is shown at theleft'side of the center of the vise g, which when the operator uses hisleft hand to turn the spindle 25 brings his body more nearly in front ofthe tool g. The table is shown inverted in Fig. 2, sothat the spindleappears to be on the right-hand side of the same, and this is also trueof the spindle shown in Fig. 4; but the projection of the obliquespindle is such that when the table is in its normal position thehand-wheel to would be outside the left-hand edge of the table, and thusenable the operator to place his body entirely in front of the tool, ifdesired. I have therefore claimed this oblique arrangement of thespindle with reference to the table and tool.

Having thus set forth the nature of the invention, what I claim hereinis 1. A shaping-machine having a frame with cross-head upon the front,and a ram movable horizontally upon the top at right angles to thecross-head, the sliding carriage h and the feed-screw'with gearing torotate the screw automatically when desired, the hearing it upon thecarriage with the rotatable nut r fitted thereto and to the cross-headfeed-screw and the carriage having an aperture h adjacent to suchbearing for the passage of a feedspindle, the table 19 detachablysecured upon the carriage and provided with means for holding awork-piece beneath the tool, a bearing carrying a spindle with its innerend extended through the said aperture in the carriage and geared to therotatable nut, and means for turning the spindle by hand, the spindleand its bearing being carried by the table, as and for the purpose setforth.

2. A shaping-machine having a frame with cross-head Z) adjustablevertically upon the front, and a ram movable horizontally upon the topat right angles to the cross-head, the feed-screw t with gearing torotate the same automatically when desired, the carriage h havingaperture h and bearing 77, having nut r fitted thereto and to the screw01 and provided with a gear for turning the nut and the bearing havingthe set-screw v for clamping the nutwhen desired, the table 29 securedremovably upon the carriage and provided with means for supporting awork-piece beneath the tool, the oblique bearings 19 and p upon thetable with feed-spindle t fitted thereto, a handle upon the outer end ofthe spindle for turning the same,.and the gear upon the inner end of thespindle adapted to pass through the aperture h in the carriage and toengage with the gear upon the rotary nut, whereby the spindle projectsthrough the foot of the table, and the handle upon the feed-spindle isextended at one side of the table, and the table and spindle areremovable together from the carriage, substantially as herein set forth.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.
